Pulse Sample Time
You can connect a digital pulse signal of up to 2KHz to the
scanner's pulse input. In this menu, you specify the pulse
sample period. (This is the second menu of the Setup
Channel Inputs menu for the pulse input channel only.)
Every sample period, the number of pulses the scanner
receives is divided by the sample time. The scanner scales
this number and uses it as the pulse channel's process
variable.
Selectable values: 1 to 20 seconds
Channel Name
This menu lets you enter a channel name (up to seven
characters) from this menu. If no name is entered, the
CAS200 will default to the current channel number.
Selectable values: A-Z, 0-9, %, /, °, space
Input Units
The Input Units menu lets you choose a three-character
description of the channel's engineering units.
• Thermocouples can only be °F or °C.
• If you have selected a linear or pulse input type, you
can choose any available character for each character
position. For example, you can use GPM or psi or % for
a linear input's units.
The table below shows the character set for input units.
